EDWARD MAKIN, JR, OF MANCHESTER, ENGLAND.

STEAM-GENERATOR;

SPECIFICATION forming part of Letters Patent No. 741,353, dated October 13, 1903.

Application filed March 3,1908. Serial No. 145,967. (No model.)

To aZZ whom it may concern:

Be it known that I, EDWARD MAKIN, J r., engineer, a subject of the King of Great Britain, residing at 40 New Brown street, Manchester, in the county of Lancaster, England, have invented certain new and useful'lmprovements in Steam- Generators, of which the following is a specification.

My invention relates to improvements in steam -generators, and particularly to those generators fitted with Makins patent cones, for which I obtained Letters Patent of the United States Nos. 599,853, 599,854, and 599,855. The cones, which are hollow Water vessels, are placed in the boiler-flue, and it is now customary to connect each cone at top and bottom by a short tube or nipple to the water-space of the boiler. It is found that in this arrangement a certain amount of scale and sediment from the interior of the boiler is deposited in the cones when the boiler 4 cools down; and the object of my improvements is to obviate this defect, as well as to improve the circulation. I accomplish this object by fitting in the mouth of each nipple or short tube, inside the shell of the boiler, on the upper or delivery side of the cones, a pipe which extends upward to above the water-level in the boiler, andpreferably terminates in a cowl or bent head,so that the water passing upward from the cone issues from the cowl or bent head of the pipe and is delivered approximately horizontally and in the steam-space of the boiler in any required direction, according to the setting of the cowl.

In the accompanying two sheets of draw= ings, Figure 1 is a transverse section of a two-fined steam-boiler in which a cowl-pipe is shown applied to the upper nipple of each hollow cone. Figs. 2 and 3 are two sectional views of a furnace-flue, taken longitudinally and transversely, respectively, and showing a cone and its cowl pipe on a larger scale. Fig. 4 is an enlarged sectional elevation of a cowl-pipe and the upper end of a cone-nipple, showing a convenient means for connecting the parts together. Fig. 5 is a plan view of Fig. 4.

In the drawings, 2 denotes the furnaceflues of a steam boiler, 3 the boiler-shell, and 4 the hollow cones or Water vessels connected to the flue 2 at the top and bottom by nipples or short tubes 5, which project a few inches into the water-space. In the mouth of each top nipple or tube 5, inside the shell of the boiler, on the upper or delivery side of the'cones, is fitted one of the cowl-pipes 6, which extends upward to above the waterlevel in the boiler and preferably terminates in the cowl or bent head shown in the drawlngs.

In Figs. 4 and 5 is shown a convenient means for supporting the cowl-pipes 6 upon the nipples 5-namely, on each pipe 6, near its base, are cast, say, three feet 7, projecting from the inside downwardly and shaped to fit and enter the mouth of the nipple, thus forming a guide and means for holding the bottom of the cowl-pipe, which coincides with and rests upon the top of the nipple. .This method of connecting the pipes 6 and 7 together allows the cowl-pipe to be readily placed in position and turned in any direction, so that the water which is heated in the cone will be delivered approximately horizontally and in the steam-space of the boiler in any required direction according to the setting of the cowl. I

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-- 1. The combination with a hollow cone connected by a nipple to the top and bottom of a boiler-flue, of a pipe, preferably cowl headed, extending above the water-level in the boiler, said pipe being rotatably and removably secured to the nipple, downwardlyextending projections on the lower end of said pipe engaging the mouth of the upper nipple, substantially as described.

2. In combination with a boiler-flue, a cone therein, nipples connecting the said cone with the boiler-flue and a cowl-headed pipe havin g a shouldered lower end fitted removably and rotatably to the nipple with its shoulder resting on the upper edge of the nipple, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDWARD MAKIN, JR.
